This article will explain in detail how to configure the layer 3 switch in the server. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Lab Topology:

Purpose: interworking between pc1, pc2, pc3, pc4 and server-pt

Lab requirements:

Pc1: ip address: 192.168.10.1

Subnet mask: 255.255.255.0

Gateway: 192.168.10.254

Pc2: ip address: 192.168.20.1

Subnet mask: 255.255.255.0

Gateway: 192.168.20.254

Pc3: ip address: 192.168.30.1

Subnet mask: 255.255.255.0

Gateway: 192.168.30.254

Pc4: ip address: 192.168.40.1

Subnet mask: 255.255.255.0

Gateway: 192.168.40.254

Server-PT: ip address: 192.168.60.1

Subnet mask: 255.255.255.0

Gateway: 192.168.60.254

The steps of the experiment:

1. Configure PC

Pc1

Pc2

Pc3

Pc4

Serve-pt

two。 Configure layer 2 switch

Operation content:

A, sw1 and sw2 create vlan10, vlan20 and vlan30, vlan40 respectively, and add the ports to their respective vlan, the ports connected to the PC set access mode and allow their respective vlan to pass, and the other ports create trunk mode and allow all vlan to pass through

B, sw3 and sw4 respectively create vlan10, vlan20, vlan30, vlan40, create trunk links for all ports and allow all vlan to pass through

Sw1:

Switch > enable

Switch#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Sw1 (config) # vlan 10

Sw1 (config-vlan) # vlan 20
